Magnetic resonance imaging (MRI), as an adjunct to ultrasonography, has become a promising tool in prenatal diagnosis and therapy. In this report, the authors described a case of giant solid mass arising in the fetal neck region diagnosed by prenatal sonographic examination at the gestational age of 33 weeks'. MRI was used to confirm the diagnosis, and to assist fetal airway assessment. Due to the concern of fetal airway compromise, the ex utero intrapartum treatment (EXIT) was strategically planned with help from specialists in the according fields. This allowed the authors to secure the fetal airway before fetomaternal circulation was disconnected. It was performed successfully through Cesarean section at the time of birth. Histopathology revealed infantile myofibroma, which is a rare form of such a tumor arising on the fetal head and neck region diagnosed prenatally.
磁共振成像（MRI）作为超声检查的辅助手段，已成为产前诊断和治疗中有前景的工具。在本报告中，作者描述了一例在孕33周时经产前超声检查诊断出的胎儿颈部巨大实性肿块病例。MRI用于确诊并辅助评估胎儿气道。由于担心胎儿气道受压，在相关领域专家的帮助下精心规划了产时宫外治疗（EXIT）。这使得作者能够在胎儿与母体循环断开之前确保胎儿气道安全。在出生时通过剖宫产成功实施了该操作。组织病理学检查显示为婴儿肌纤维瘤，这是一种罕见的在产前诊断出的发生于胎儿头颈部区域的此类肿瘤。
